"The present invention relates to those windows which have coupled sashes and which swing on.

pivots which are arranged about in the middle between the head and the sill of the frame, and which are locked at the sill. It is known to seal the vertical spaces between the frame and the sashes by T-shaped sealing lists which are divided into portions located on each side of the pivots. The; lists arranged on the one side of the longitudinalaxis of the pivots, i. e. the swinging axis, are in this case set in from the inside, through the innersash and the frame and fixed to the inner-sash. The lists arranged on the other side of the swining axis are. set in through the frame and fixed thereto and extend through a recess of the inner sash. These T- lists are cumbersome to manufacture and to fix in their positions. Furthermore, much woo-d material is lost at their manufacture and fixing in the sash and in the frame respectively.

The invention is substantially characterized in that the sealing list is L-shaped, and that each portion thereof arranged on the one side of the horizontal axis is fixed with its web to the inner sash in such a manner that in the closed position of the window the top of the web of the sealing list and the inner face of the flange of same parallel to said top rest against faces in recesses of the frame, while each portion of said sealing list on the other'side of the horizontal axis is fixed with its web in a recess of the frame in such a manner that the top of the web of the sealing list and the inner face of the flange of same parallel to said top rest against the outer sash and against a face in a recess of the inner sash respectively.

According to the invention the web of the sealing list may extend so far as to rest against a face formed by recesses in the outer sash and in the frame. According to the invention each of the sashportions at right'angles to the horizontal axis may be curved in such a manner that during the closing movement the upper sash portion which is parallel to the horizontal axis, will first rest against the window frame and then the lower portion. The sash portions at right angles to the horizontal axis are divided into lamellae which are glued together.

The invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a front view of the window, Fig. 2 is a 7 cross section of line II-II in Fig. 1, Fig. 3 is a cross section on line III-III in Fig. 1. Figs. 4 and 5 show a modified embodiment of the sections according to Figs, 2 and 3. Fig. 6 is a modi- 2 Claims. (01. 20-53) 2 fication of a portion the sashes from the side at the pivot. The reference numeral 2 denotes the frame, and 3 and 4 denote the outer and the inner sash respectively. The sashes are rotatable about a horizontal axis or pivots 5 which by means of a fitting 6 is fixed to the frame 2 and the inner sash 4.

" As will be seen from Figs. 2'and 3 an L- shaped sealing list I is according to the invention used for sealing each ofthe vertical intermediate spaces between the frame 2 and the sashes 3and 4, said list being divided into one part arranged above the axis 5 and another part arranged below said axis. Each upper part is with its web fixed in a recessin the inner sash 4 so that the top of the web of the sealing list and the inner face 1a of the flange of said sealing list in the closed position of the window (see Fig. 3) rest against faces 8 and 9 respectively in a recess of the frame 2. Along the faces 8 and 9 are made grooves ID in the sealing list and in the frame for sealing strips Illa. or the like. Each lower part of the sealing list is with its web fixed in a recess of the frame 2 so that the top of the web of the list and the inner face 1a of said list in the closed position of the window (see Fig. 2) rest against the outer sash 3 at H and against a face l2, respectively, in a recess of the inner sash. Along the faces II and [2 are made grooves I3 for sealing strips [301. in the sealing list and in the outer sash and the inner sash respectively.

As will be seen from Figs. 4 and 5 the vertical web M of the sealing list 1 may be made so long that it projects, with a surface [5, into a recess in the outer sash 3 and, with another surface I6, into a recess in the frame. In other respects, the embodiments according to Figs. 4 and 5 are identical with the embodiment according to Figs. 2 and 3. In this case the grooves I! in the outer sash and in the sealing list, and in the sealing list and in the frame respectively, are made for inner sealing strips Ila. According to Fig. 4 the sealing list is secured in a recess in the frame and according to Fig. 5 in the inner sash 4.

In large swinging windows it is a disadvantage that the two sash portions which are parallel to the horizontal axis, contact the frame at the same time because an effective tightening of the contact surfaces of the sash and of the frame 7 by means of a locking device provided at one of said sash portions is prevented. For this reason those port1ons of the sash portions which are located at right angles to the horizontal axis,

of the window-frame with i have according to the invention been given a curved shape so that during the closing movement that portion which is located on the opposite side from the locking device parallel with the horizontal axis first will rest against the window frame and then that portion where the locking device is arranged.

Fig. 6 is a modification showing the curvatures on an exaggerated scale. The sealing lists 7 are supplemented by sealing strips shown at Illa in Fig. 3 and l3a in Fig. 2. The portions of the window sashes which form right angles with the axis of rotation, i. e. the vertical portions, are

slightly curved inwardly toward the window frame at their tops in such a manner that the upper portions 18 of the sashes, which are parallel to the axis of rotation, will come into contact with the frame before the lower sash'portions 19. This results in very satisfactory sealing between the frame and the sashes. In order that the vertical sash portions may retain their curved shapethereare glued together the lamellae zfl and 21, theglued surfaces of these lamellaebeing parallel with the surfaces of thesashes which are in contact with each other.

Having now described my invention, what I claim as new anddesire to secure by Letters Patent is:

1. A window construction having a doublesashed unit mounted on. pivots in a frame to swing, about a horizontal axis located midway hetween head and sill ofsaid frame and lists divided into portions arranged on each side of said axis being providedforsealing the intermediate space extending atright angles to said horizontal axis and between saidframe and said unit, said sealing lists being L -shaped, and each portion thereof arranged on the upper side of said horizontal axis having its Web fixed to the inner sash of said unit in such a manner that in the closed position of the window the top of the web of the sealing list and the inner face of the flange of same parallel to said top rest against faces in recesses of the frame, while each portion of said sealing list arranged on the lower side of said horizontal axis has its web fixed in a recess of the frame in such a manner that the top of the web of the sealing list and the inner face of the flange of same parallel to said top rest against the outer sash and against a face in a recess of the inner sash respectively.

2. A window construction as claimed in claim 1,

'5 in which said web of the sealing list extends so far as to rest against face formed by recesses in the outer' sash and in the frame.
